google/veyron*: change .ddrconfig from 14 to 3
There are two configs, sdram-lpddr3-hynix-2GB.inc and sdram-lpddr3-samsung-2GB-24EB.inc that use .ddrconfig = 14. Changing .ddrconfig from 14 to 3 improves performance especially on contiguous memory accesses. Comparing the .ddrconfig: - if .ddrconfig = 3, C RDRR RRRR RRRR RRRR RBBB CCCC CCCC C--- - if .ddrconfig = 14, C DRBB BRRR RRRR RRRR RRRR CCCC CCCC C--- where - R: indicates Row bits - B: indicates Bank bits - C: indicates Column bits - D: indicates Chip selects bits .ddrconfig = 3 has multiple banks switching which improves DDR timing.
